三甘醇溶剂脱水天然气的露点降不高于（）

A、沸点较高（288℃），再生温度高，贫液浓度可达98%~99%，因而，露点降比二甘醇多13～30℃; The boiling point is high (288℃), the regeneration temperature is high, the concentration of lean liquid can reach 98%~99%, so the dew point drop is 13 ~ 30℃ more than diethylene glycol.

B、蒸气压较低，27℃时仅为二甘醇的20％，因而被天然气携带损失小; The vapor pressure is low, only 20% of diethylene glycol at 27℃, so the loss caused by natural gas is small.

C、热稳定性更好，理论热分解温度为206.7℃，二甘醇为164.4℃; Thermal stability is better, theoretical thermal decomposition temperature is 206.7℃, diethylene glycol is 164.4℃;

D、脱水操作费用比二甘醇低。Dehydration costs are lower than diethylene glycol.

A. 沸点高

B. 蒸汽压较高

C. 热力性质稳定
